FORMULA
Empirical for column k:
k=1: a(n) = 4*a(n-1)
k=2: a(n) = 4*a(n-1) -4*a(n-3) +a(n-4)
k=3: [order 8]
k=4: [order 12]
k=5: [order 16]
k=6: [order 19]
k=7: [order 22]
Empirical for row n:
n=1: [polynomial of degree 7]
n=2: [polynomial of degree 7]
n=3: [polynomial of degree 7] for n>1
n=4: [polynomial of degree 7] for n>2
n=5: [polynomial of degree 7] for n>3
n=6: [polynomial of degree 7] for n>4
n=7: [polynomial of degree 7] for n>5
